Kodi zifukwa kuzimitsira deformation chifukwa kutentha mankhwala a ng’anjo yamagetsi yoyesera

1. Kutentha kosagwirizana ndi kuziziritsa

Gawo lomwelo limatenthedwa mu ng’anjo yamagetsi yoyesera, mbali imodzi ndi mbali ina pafupi ndi thermocouple, mbali yakutsogolo ndi kumbuyo kwa ng’anjo, malo okhudzana ndi malo osagwirizana ndi gawo, etc., zonse zimakhudza kutentha. Yesetsani kusunga kwa nthawi, kutentha kwa pamwamba kumakhala kofanana, koma kutentha kwenikweni ndi nthawi yogwira kumakhala kosiyana kulikonse, ndipo kusintha kwapangidwe kwa kuzimitsa ndi kuzizira kumasiyananso. Zotsatira zake, kupsinjika kosasunthika kozimitsa kumabweretsa kusinthika kwa magawo. Kuzizira kosagwirizana kungayambitsenso kupsinjika kosagwirizana ndi kusinthika, monga kusuntha kosagwirizana, kutentha kwa gawolo popanda madzi ozizira kumawomba pang’onopang’ono, ndipo mafuta oyamba ndi mafuta achiwiri amayambitsa kuzizira kosagwirizana, komwe kumabweretsa kuzizira kosiyana. Uniform deformation.

2. Kutentha kwa kutentha ndi nthawi yogwira

Kuchulukirachulukira kutentha kuzimitsa, kutalikitsa atagwira nthawi ya experimental ng’anjo yamagetsi, ndi kukhalapo kwa flake pearlite kapena punctate pearlite mu kapangidwe choyambirira poyerekeza ndi yachibadwa ozungulira pearlite, zonse kumawonjezera quenching matenthedwe kupsyinjika ndi kupsyinjika kwa bungwe, potero kuonjezera kuzimitsa kwa mbali Zopunduka. Choncho, pofuna kuchepetsa mapindikidwe a mbali, yesetsani ntchito m`munsi quenching kutentha ndi yoyenera atagwira nthawi, ndipo pa nthawi yomweyo amafuna dongosolo choyambirira cha pearlite ozungulira ndi kukula yunifolomu.

3. Kupanikizika kotsalira

Zigawo zozimitsidwa zikakonzedwanso, zopindika zazikulu nthawi zambiri zimapangidwa. Ngakhale mbali zozimitsidwa zimatenthedwa ndi kutentha kwa moto mu ng’anjo yamagetsi, ndipo kutentha kumasungidwa kwa nthawi ndithu, zidzatulutsanso zowonongeka kwambiri. Izi zikuwonetsa kuti kupsinjika kotsalira kuli mung’anjo yamagetsi yoyesera. Adachita nawo ntchito yotenthetsera. Ziwalo pambuyo kuzimitsidwa ali mu mkhalidwe wosakhazikika maganizo, ndi kupsyinjika yotsalira si kutulutsa lalikulu mapindikidwe kutentha firiji. Chifukwa malire otanuka achitsulo ndi okwera kwambiri kutentha kwa chipinda, pamene kutentha kumawonjezeka, malire otanuka amatsika mofulumira. Ngati kutentha kwachangu kumathamanga kwambiri kuti athetse kupsinjika kotsalira panthawi yotentha, kutentha kwakukulu kumasungidwa. Pa kutentha kwakukulu, ngati malire otanuka ndi otsika kusiyana ndi kupsinjika kotsalira, kusinthika kwa pulasitiki kudzayambika, ndipo ntchitoyo idzakhala yowonekera kwambiri pamene kutentha kwa kutentha sikuli kofanana.
